1.When the power is turned on, the fan does not rotate and does not display.
Cause of failure: fuse blown
Treatment method: replace with a new fuse (2A)
2.Poor stability.
Cause of failure: unstable light source voltage
Treatment method: check whether the input voltage meets the requirements of the machine
3.Poor repeatability.
The cause of the failure: air bubbles are generated when the sample is sucked
Treatment method: rinse with absolute ethanol for 2-3 times, then rinse with distilled water for 1-9 times
4.The printer does not print.
Cause of failure: poor contact of the plug or lack of paper
Solution: Replace the printing paper
5.The operation buzzer does not sound, and the operation fails and freezes.
Cause of failure: due to external grid interference or misoperation
Solution: Shut down and restart to run
6.The boot display is cluttered.
Cause of failure: This phenomenon is generally caused by grid interference
Solution: Turn off the power switch, wait 10 minutes and then restart, install a better quality regulator
7.Pump rotation, no sample injection
The cause of the failure: the suction tube is blocked or the silicone tube is aging
Treatment method: replace the suction tube or silicone tube
